EXTENSION-MAGAZINE FOR COAL-STOVES.

SPECIFICATION forming part of Letters Patent No. 240,056, dated April 12, 1881.

Application filed February 1, 1881. (No model.)

Toall whom it may concern:

Be it known that I, Dnwrrr VAN EVERA, of Maquoketa, in the county of Jackson and State of Iowa, have invented a new and useful Improvement in Extension-Magazines for Goal-Stoves, of which the following is a specification.

Figure l is a side elevation of my improvement. Fig. 2 is a sectional elevation of the same. Fig. 3 is a sectional plan view of the same, taken through the line a: :10, Fig. 2.

Similar letters of reference indicate corresponding parts.

The object of this invention is to facilitate the use of diti'erent kinds and sizes of coal in the same magazine and insure the proper feed of, the coal to the fire-box.

Theinvention consists in constructing an extension-magazine of a stationary or movable upper part having exterior ribs, and a movable lower part made in two or more sections, and having corresponding interior grooves, wherebythe magazine can be lengthened and shortened; and also in the combination, with the stationary or movable upper part having slots, of curved plates and operating-rods attached to the said plates and passing through the slots in the said upper part, whereby the coal can be loosened and caused to pass down to the fire-box, as will be hereinafter fully described.

A represents the upper part of the magazine, which may be stationary or movable, and which is suspended over the fire-box of anycoal-burning stove in the ordinary manner.

Upon the outer surface of the lower portion of the part A are formed ribs B, to fit into grooves O in the inner surface of the lower or adjustable part, D. The lower part, I), is made in two longitudinal halves or sections, which are connected to each other at one edge by hinges E, and are provided near their other edges with perforated lugs F, to receive the bolts G, by which the said sections are drawn together to firmly clamp the upper part, A, of the magazine. The ribs B and grooves O are equidistant, so that by loosening the bolts G the lower part, D, can be raised and lowered to lengthen and shorten the magazine, as the size and kind of coal to be used may require.

H are plates curved to fit against the inner surface of the upper part, A, of the magazinc, and which may have their inner surfaces either smooth, roughened, or ribbed, as desired. The plates H are placed upon the opposite sides of the magazine, and to the the rods I that pass in through the sides of the part A maybe braced or forked, so that they will hold the plates H more firmly and keep them in place securely. The outer parts of the rods I are curved so that their outer ends will meet at the side, front, or b ack of the stove, and are provided with a knob, J, or other ornamental handle.

With this construction, by operating the rods I the plates H will be vibrated to loosen the coal should it be clogged, and cause it to feed down into the firebox.

To the parts of the rods J that pass in through the sides of the part A and through the stove are attached washers K, of such a size as to always cover the slots through which the said rods pass.

1n the side of the upper part of the part A of the magazine is formed a longitudinal slot L, through which a rod may be passed to assist in dislodging the coal should it become clogged, and thus cause it to feed down.

The parts of the magazine are designed to be wholly or chiefly made of cast-iron.

Having thus fullydescribed-my invention, 1 claim as new and desire to secure by Letters Patent 1. An extension-magazine for stoves, constructed substantially as herein shown and described, consisting of the stationary or movable upper part, A, having exterior ribs, B, and the adjustable lower part, D, made in two or more sections, and having corresponding interior grooves, 0, whereby the magazine can be lengthened and shortened, as set forth.

' 2. In an extension-magazine for stoves, the combination, with the stationary or movable upper part, A, having slots M, of the curved plates H, and the operating-rods I, substantially as herein shown and described, whereby the coal can be loosened and caused to pass down to the fire-box, as set forth.

DEWITT VAN EVERA.
